Longworth was a Baker Act patient who had been released but wanted to stay longer, the affidavit states. The state’s Baker Act allows people to be involuntarily committed to a facility for psychiatric evaluation.

Longworth initially told police he wanted to kill his roommate, but later said he wished the roommate didn’t die and was sorry.

Longworth was held Friday in the St. Lucie County Jail on $100,000 bail, a jail official said.
